MySQL Error 1322: Cursor Statement Must Be SELECT
Description
Error 1322 indicates that a `DECLARE CURSOR` statement in a MySQL stored procedure or function is attempting to use a SQL statement that is not a `SELECT` query. Cursors are designed to iterate over result sets, which can only be generated by `SELECT` statements, not DML operations like `INSERT`, `UPDATE`, or `DELETE`.
Error Message
Cursor statement must be a SELECT
Known Causes
3 known causesNon-SELECT Statement in Cursor Declaration
The `DECLARE CURSOR` statement specifies an SQL command other than `SELECT` (e.g., `INSERT`, `UPDATE`, `DELETE`, `CALL`) as its underlying query.

Misunderstanding the purpose of cursors, the developer tries to perform data modification language (DML) operations directly within the cursor's declaration.
Incorrect Stored Procedure Logic
A logical error in the stored procedure or function leads to a non-`SELECT` statement being assigned to a cursor, indicating a design flaw in the procedure.
